lets expand on this idea.. augment reality overlay showing the resulting code in what you are looking at.. persistence is the ground.. model + business logic is the surroundings.. API is in the clouds..
Actually would pair better with functional programming.. as in the flow of the data - all those filter and mappers.. would fit well into the way you walk upon. But what is the center of your viewpoint and the center of attention, while you are moving. You would need to have a modal mode.. one where you move through the code structure by walking and/or looking and one - where the center is stationary, even while you move.
